Q. How do I reference more than one item by the same author in the same year?
When you have two references by the same author that were written in the same year, it becomes hard to tell them apart. To make things clearer, we use the letters a,b,c etc, after the year, both in-text and in the reference list. The letter a is given to the work whose title comes first alphabetically.
